Ethereum had 40* growth rate over last 2 years.It is a decentralized platform that runs smart contracts:application that runs exactly as programmed without any possibility of downtime,censorship,fraud or any third party interface.Ethereum have incresed a lot in recent mont and i am sure that its value will keep increasing.I think the only cryptocurrency that has the ability to overtake Bitcoin is Etherum in my view so it is worh to invest on Etherum.
